ventionlt-o provideanoscillatory heater mixer in w-hi'ehA means arepositmnedf `within the tanltwh-ich agitate 1the material `while it is directing-a heating medium into the material.

A-further object of the invention isto provide an oscillatory heater mixer in whichi theheatingot themateriali maybe started (lu-ring the initial filling. of the tank 'without 3 scorching-any of the material.

A further ob-ject of the invention is toipro- Videan oscillatory heater mixer in which the` materiali is agi-tatedfby oscillating radiali arms `and steam directing tubes to expedi- 'l tiously heat all portions of'v themateriali tola uniform. tenqoerature.A

A further object vofthe?. invention: is vto* provide an oscillatory-heatenmixerhaving a brine/sank for directly charging thebatch A of material beingy mixed lwith .-a measured quantity of brine.

A further object of'thein-venti-on is to pro-A vide an oscillatory heater mixer in which thefamount .of brine tov belmixed with the n batch'of? material inpthe tank is visible to and under the control of the operator.

A further object of the invention is to provide a combined heater and mixer for materials such as corn and liquid, wherein the mixing devlce 1s movable only through the lower portion of the batch of mixture and the heating Huid is simultaneously injected, so as to permit the air to escape upwardly Vthrough the mixture while the heating fluid i follows the escaping air.

A further object of the invention is to provide an oscillatory heater mixer having an angled bottom portion for directing the material towards the discharge end of the tank.

A further object of the invention is to provide an oscillatory heater mixer which is of simple construction, is strong and durable and is well adapted for the purpose described.

W'ith the abovey and`r otherobjects in View. the inventionconsists ofi the improved oscil'L latory heatermixer and its parts andi combi-l nations asset fforth in the claims, and all equivalents-fthereo. f

The tanks are supported upon frame legs 20 and are also;v eonnected.ftogether by' a bracket frame 21 of angular formation, which is bolted to the front portions off-.the tanks.

The rock shafts 13' extend lthroughrand are,l journaled in said bracket rame,and the.

frame isgjalso formed With vcentral bearings 21 and 22in1which are-j-ournaled'short shafts 23 and 24. A loose -pulley 25"-is journaled on the outer end portion of the shaft 234 and next thereto a pulley 26 ismounted fast on the shaft tok drive the same. A gear Wheel 27 also mounted fast on the shaft 23meshes with and drives a larger gear Wheel 28 which is mounted fast on the lower short shaft 24. The gear 28 is provided with a lWrist pin 29 and the outer end portions of the rock shafts 13 Y have dependingl crankarms 30 -mounted `fast thereon which are pivotally connected tothe Wrist pin by links 31 so that the rotation 'of the gear Wheel 28 Will .rockthe tubular shafts 13 as indicated by dotted lines in Fig. 4.

A brine tank 32 mounted lin spaced relation on brackets 33 connected to the fixed portion 11V of the tank cover, has depending discharge pipes 34 Which extend through the cover part 11 and into the tanks and are provided with valves 35 for controlling the amount of brine supplied' to the tanks. glass gauge A36 forming partzothe brine'v tafnkpermits View of the amount of brine being discharged from the brine tank..

The mixing tanks 8 are each provided with afgaufge 37 vto indicatefthe amount of material being mixed in each tank'. It is to beunderstood that the'invention contemplates ithe use of one 'or more mixing tanks Without departingfrom the Spirit of the invention. g

From thefo'regoing 'description itv will be seen that it is only necessary to turn on'the 'steam an'dstart loading the tanks yvith the material to be heatedand mixed and then open the brine tank valves to charge the mixing tanks Withv the desired amount of brine.`

AsV the U-shaped member oscillates it will direct the steam jets into different and constantly` changing portions of the material being heated Without liabilityl of scorchingv same. Thel novel construction also provides for all portions of the material to be cooked to the same degree.

What I claim as my invention is:

1. In combination, a mixing tank, means for introducing material to be treated into said tank, a support oscillatable about a horizontal axis Within said tank, a horizontal perforated-tubular member depending Ifrom said support and movable thereby only through the lowermost portion of said tank, meansA for injecting iuid into said tank through thenperforations of said member, and `paddles A4carried by said support and movable .thereby `only through upper portions of said tank.v

2. In combination, a mixing tank having a bottom curved about a horizontal axis extending longitudinally through said tank,

means orintroducing material to be treated portion only of eaohof said tanks about said axis of curvature of the bottom, means for injecting fluid into each of said'tanks through the perforations of the tubular member therein, paddles oscillatable Within the upper portion only-of each of said tanks about said axes, and common means for oscillating all of said tubular members and paddles in unison.

In testimony whereof I affix my signature.`
